How to display not the whole array, but a part?

Question

JavaScript

Good afternoon, there is a file: array.json, it contains 100500 objects. When this document is requested, all 100500 items are displayed.
And then a logical question arose: how to display not 100500 elements on the page, but 100, and then another 100 when clicking, and another 100 when the next click.
I tried to write something like a condition on the length of the array, but! didn't work...
A real example, like a contact wall, only there the loading goes to the very end when scrolling.
Well, or like in online stores, at the bottom there is a button for 20 more elements ...
Or at least what this thing is called to find an example and figure it out.
Thanks

If you can change the server logic - add parameters to the request - from which record to return data - pagination is called. Well, then get JSON data in portions.
